This study examined the effect of the Collaborative Problem-Solving for Character Competence (CoProC) instruction model within the context of secondary science education. The participants of this study were comprised of 143 Korean students, each of whom was in the 10th grade spread across four class cohorts. These cohorts were further divided into an experimental group (comprised of 73 students from two different classes), which received the CoProC program; and a control group (70 students from two other classes), which did not. In order to assess the effect of CoProC instruction model upon participants' character competence, we designed and administered a Character Competence Test for participants. The CoProC instruction model consists of 3 fundamental steps: Preparation, Problem-solving, and Evaluation. Key character competence targeted in the CoProC program include caring, collaboration, communication, responsibility, respect, honesty, self-regulation, and the development of positive self-image. Thus, these same qualities were targeted and analyzed in the Character Competence Test, which was administered before and after the CoProC activities. The results show a significant increase in the experimental group's competency for caring, collaboration, responsibility, respect, and self-regulation when compared to the control group. Based on these results, we have found that CoProC instruction model to be an effective teaching intervention toward cultivating character competence in a secondary science education setting.

Collaborative Filtering (CF) suffers from two major problems:sparsity and cold-start recommendation. This paper focuses on the cold-start problem for new customers with no purchase records and the sparsity problem for the customers with very few purchase records. For the purpose, we propose a method for the new customer recommendation by using a combined measure based on three well-used centrality measures to identify the customers who are most likely to become neighbors of the new customer. To alleviate the sparsity problem, we also propose a hybrid approach that applies our method to customers with very few purchase records and CF to the other customers with sufficient purchases. To evaluate the effectiveness of our method, we have conducted several experiments using a data set from a department store in Korea. The experiment results show that the combination of two measures makes better recommendations than not only a single measure but also the best-seller-based method and that the performance is improved when applying the hybrid approach.

The purpose of this study is to identify the effect of Problem-Based Learning on Student's Creativity Ability in Middle School Science Class. The experimental group had Problem-Based Learning classes for six weeks and control group had traditional inquiry instruction for the same period. The results of this study presents that Problem-Based Learning is significantly effective for the improvement of creative skills test and creative tendencies. And PBL group student's had positive thinking for PBL. It's not easy to generalize these results because of many different variables. but the results suggests that teachers should make an effort to improve student's creativity applying Problem-Based Learning. And it's necessary to develop many kinds of problems and teacher's instruction method to enrich creativity in the process of Problem-Based Learning.

The purpose of this thesis was to implement effective blended PBL(Problem-Based Learning) systems for information communication ethics education. The proposed systems, Online learning and face-to-face classes were systematically combined and Moodle is used for online learning platform. We proposed the use of wikis and blogs not just for creation of knowledge, but as active learning tool to support PBL. In the proposed system, learners used the web 2.0 as a open place to create new knowledge and experience various effects of PBL, such as (1) Improvement of problem solving ability, (2) Understanding of cooperative learning. The blended PBL systems with teaching and learning model were evaluated learners' level of satisfaction and educational achievement in the study of information communication ethics. The result shows that blended PBL learning method is more effective in cultivating consciousness of information communication ethics and showed more higher level of learners' satisfaction and educational achievement than the face-to-face PBL learning method.

구성주의에 기반한 7차 교육과정에서 교사 중심의 수업에서 학생 중심의 수업으로 전환을 강조하고 있다. 또한 지식을 객관적인 존재라는 의식에서 벗어나 학생들 스스로에 의해 구성되어진다는 것을 강조하고 있다. 이러한 시점에서 교실 수업의 개선은 당연한 흐름이며 교사들의 의식 전환 또한 당연한 것이다. 7차 교육과정에서 문제해결력을 바탕으로 한 수학적 힘의 신장을 강조하고 있다. 이러한 시대적 요청에 부응하는 교수법의 개발에 있어서 문제해결력과 창의적 사고력 학습법에 대한 연구는 필연적이다. 따라서 본 연구의 목적은 어떤 문제설정 방법이 문제해결력과 창의력을 향상시키는데 보다 더 효과가 있는지 알아보는데 그 목적이 있다.

Purpose: This study was to identify the types of subjectivity on PBL experience of freshmen in nursing students. Method: This study is exploratory research through Q methodology. From 102 Q populations, we selected 31 Q sorting was done by 25 of P sample. When the Q sorting is completed on nine point scale, we interviewed participants and documented their responses. The data was analyzed by using QUNAL program. Result: The result of the study showed 4 types. Four factors provided an explanation for 71.6% of total variances, and these four factors were analyzed and categorized as four types. We named type 1 as [positive pressure], type 2 as [relational friendly], type 3 as [creative benefit], type 4 as [paticipatory development]. Conclusion: In this study, PBL was valuable experience and recognized as a variety of perspectives for freshmen in nursing students. These findings indicate we suggest that planning of strategy for efficient operation on PBL was reflected above results.

The ethical problems related to climate changes have basically different character from the ethical problems which we have experienced until now. In order to approach ethical problems of climate changes for forseeing, mitigating and adapting many complicated situations which result from climate changes we should breake away from the point of anthropocentrism at first. Secondly, the education of the ethics of climate changes is very important in all levels of schools. It is very important and urgent to decide what and how we should teach. Finally, the sustainability has important role in the justification of why and what we should take actions against climate changes.

The purpose of this study was to develop and implement a home economics convergence education program applying problem-based learning method focusing on the middle school food and nutrition life unit, and verify the effect of this class on the problem-solving ability of students. For this, the study set up the theme of 'sustainable life' by examining the relationship with other subjects, and set the key question as 'what is the relationship with the environment of food resources, the influence of individual level, and the solution method?' was postulated. And developed the problem and the total of 8 classes. As a result of conducting the convergence education program with home economics applying problem-based learning method, the pre-test and post-test scores were 3,54 and 3.96, respectively, which showed a significant increase in problem-solving ability (p<.001). There were significant differences in the dimensions of problem-solving ability, except for problem clarification. Therefore, it was confirmed that the home economics and convergence education program applying problem-based learning method is an effective class for improving students' problem-solving ability.
